Rear Wheel Alignment
« on: Mar 09, 2012, 11:51:08 »
Looking for some advice here.

With pads out, it looks like the rear disc appears to be brushing the caliper.
Bearings were replaced when I had the wheels coated, could the collar not be all the way fastened causing excess space?
If I recall, it's all the way down as far is it would go, could the bearing not be all the way pressed in?

Not sure if you can tell from the picture, but does this look like the bearing is pressed in all the way?
My gut tells me no.

I think I've got it.
There's a spacer in between bearing that I don't think was sitting right.
I was able to seat the bearing a little bit futher down, seems more flush now.

Looks like that did it.
What's the best way to square up the rear wheel? It's not like I can adjust the angle of the caliper...

Never mind. I'll adjust the drive chain adjusters on each side til it seems even

Pushing sprocket side bearing in won't have any effect on caliper mounting bracket.
 The caliper is offset too far, bracket is bent or PC under rotor on mounting faces is spacing things out
 How does it locate, torque arm near swing arm pivot or lug on swing arm near axle?

It was the bearing on the caliper side that wasn't flush like the sprocket side was. It's better, but I'm not certain it's 100%. I still think it's off by a couple mm.

I was able to get the new pads in, but the wheel has lots of friction. Not free spinning like I would think, unless that much is expected.

The pic of the sprocket side was to show how it's sitting flush, unlike the pic before it.

When you say lots of friction do you mean the brakes are grabbing, or will the wheel turn with slight pressure, it's normal for new pads to brush the disc until they bed in, if the pads have not been changed in a long time the pistons may not be moving freely. I fitted new pads last year on my 30 year old Beemer and the wheel was quite stiff, however after a couple of miles the pads were bedded in and the wheel was running free.

Well, it's not like the pads dropped in. One side was easy, the other took some force. I'll ride it for a few miles, I can always start over...

I know I've shimmed them in the past, 0.020" to move caliper mount over slightly.
 Don't remember if it was Honda, Yamaha or Suzuki though (maybe all of them at one time or another)

Old style RD calipers often (always ?) need to be shimmed. That may be a simple solution here too. a pair of shim washers would work fine.
